Versions
DMI 1.0, introduced in 2004 with a data transfer rate of 1 GB/s with a ×4 link.
DMI 2.0, introduced in 2011, doubles the data transfer rate to 2 GB/s with a ×4 link. It is used to link an Intel
DMI 3.0, released in August 2015, allows the 8
In 2021, with the release of 500 series chipsets, Intel increased the amount of DMI 3.0 lanes from four to eight, doubling the bandwidth.[11]
DMI 4.0, released on November 4, 2021 with 600 series chipsets, doubles the bandwidth each lane provides and is two times faster when compared to DMI 3.0. The number of DMI 4.0 lanes depends on chipset model used.[12]
Implementations
2005 Centrino mobile platform.[2]: 3 At the time DMI linked the GMCH and I/O Controller Hub.[2]: 3
Northbridge devices supporting a northbridge DMI are the Intel 915-series, 925-series, 945-series, 955-series, 965-series, 975-series, G31/33,
]Processors supporting a northbridge DMI and, therefore, not using a separate northbridge, are the
Southbridge devices supporting a southbridge DMI are the ICH6, ICH7, ICH8, ICH9,
